ENGLISH SUBTITLE AVAILABLE!! Metal Casting Casting our first copper ingot with my homebuilt charcoal foundry. We didn’t achieve to melt the copper on our first try since our first lid let to much heat escape, so we built a huge and heavy lid from a boardwalk plate, isolating it with some fire cement and also put a second metal plate as lid on the crucible itself for keeping the temperature better. Now, after pre-heating the foundry for about 15 minutes, we put the crucible inside and had about 2 kg of copper melt in another 10 minutes. The mold is a simple cake tin which is fortunately shaped like ingots are, so this worked out perfectly.
